    Win 8.1.1 Idle/Random sleep, Sleep Reason: Application API

    Hey there everyone,

    Long-time lurker and technician here, thanks for all the assistance in the past and future.

    I've encountered a sleep-related problem on my tower (desktop). Some time after a long idle (~12-16 hours), my machine just goes to sleep. I require this machine to be up 24/7, so I've tried many things; inevitably, my computer just decides to take a nap. I've even enabled wake-on-lan so I can wake it up remotely when I'm not nearby. Attached are my system specs/info, service culprits (non-microsoft), and attempted fixes.

    systeminfo.txt is output from systeminfo
    AidaReport.txt is a full summary of my machine
    SleepEvents.txt contains the sleep event itself and the events that always seem to follow or precede it.

    Running Non-Microsoft Services:
    Adobe Acrobat/Flash Player update Services
    AMD External Events Utility
    Apple Mobile Device
    Bonjour Serivce
    Evolve Service (Evolve Gaming Client)
    FileZilla Server FTP server
    Fitbit Connect Service
    iPod Service
    Mozilla Maintenance Service
    OpenVPN Service
    Splashtop Remote Service
    Splashtop Software Updater
    Steam Client Service
    VMware Authorization Service
    VMware USB Arbitration Service
    VMware Workstation Server

    Things I've tried:

    Disabled all sleep related settings, including hybrid sleep and fast startup. Power options are set to never sleep on all profiles (power plans). I've tried Caffeine (F15 every 59 seconds) and Insomnia (SetThreadExecutionState).

    Originally, my computer was going to sleep with the reason Sleep Button pressed, and it looked like it was my keyboard (Razer DeathStalker), so I disabled the hardware sleep button, then the reason changed to Application API (with some delay between the 2 problems).

    All windows updates have been applied, including the latest 8.1.1.

    I apologize if there is a thread detailing a fix or an API recorder of some sort, I have been unable to find either of those in my weeks of research. Please let me know if there is any other information I can provide.

    Thanks again!

    I saw that thread. Not only is that difficult to sort through, but my problem is exactly the opposite. It goes to sleep randomly, it certainly doesn't refuse to sleep X)

    One thing I have done since then is turn off the ability for the computer to disable the network card through the driver settings (power management tab). We'll see if that does something. If anything, at least it will guarantee my ability to use Wake-on-LAN.

    Computer went to sleep after my attempted fix (network card power management). I have now set MaintainServerList (\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters) to No and disabled the Computer Browser (governing) service. I'll report back if it happens again. Thanks!

    Any results to report, nok0?

    I found this thread after my Win8.1 machine just took a nap when it should not have. My power settings are configured to never send the PC into sleep mode. And while I was in the middle of a huge (19+GB) download, it went into sleep mode, and now I'm quite irritated. The Event Viewer says only:

    The system is entering sleep.
    Sleep Reason: Application API

    ...which doesn't tell me much.
